Corales De Las Islas Canarias
ETSI MINAS (UNIVERSIDAD POLITÉCNICA DE MADRID) CORALES DE LAS ISLAS CANARIAS FICHERO Ignacio Alonso Provencio Lorena Blanco Muñoz Marzo de 2013, Prácticas en los laboratorio del IGME 1 CONOCIMIENTOS PREVIOS SOBRE LOS CORALES: ANATOMÍA Los corales marinos son animales coloniales, salvo excepciones, pertenecientes al filo Cnidaria, clase Anthozoa. Las colonias están formadas por hasta miles de individuos zooides y pueden alcanzar grandes dimensiones. Las distintas especies de invertebrados con los que vamos a tratar perteneces al grupo de los antozoos, es decir, cnidarios que sólo tienen una fase pólipo (carecen de fase medusa) y poseen una cavidad gástrica dividida en compartimentos. El término "coral marino" suele usarse para designar a los antozoos; los corales se dividen en blandos y duros (en función del exoesqueleto que presenten), según tengan esqueleto o no: - DUROS: antozoos que generan un esqueleto calcáreo duro, especialmente si construyen colonias ramificadas. También son comunes las especies que forman colonias compactas incluso con un esqueleto córneo y flexible. - BLANDOS: son antozoos pertenecientes a las especies del orden Alcyonacea, que no generan esqueleto y utilizan el calcio en forma de espículas (unidades esqueléticas calcáreas o silíceas que forman parte del esqueleto de los poríferos) repartidas por su tejido carnoso, para proporcionarles mayor rigidez y consistencia. La perspectiva embriológica de los cnidarios es uno de los aspectos más importantes; normalmente el zigoto da lugar a una blástula con un espacio interior o bien, da lugar a una blástula maciza. Los antozoos, poseen tres capas de tejidos plenamente desarrollados: - ECTODERMO: capa celular primaria más externa del embrión. Da lugar al sistema nervioso, órganos especiales de los sentidos, la epidermis y derivados epidérmicos. -

Anthozoa. Nat. Croat., Vol. 11, No. 3., 265–292, 2002, Zagreb. Fifty-two anthozoan species were recorded and collected in the area of Mljet National Park dur- ing surveys from 1995 to 1998. General and ecological data are presented for each species, as well as distribution and local abundance. Recorded species account for about 60% of anthozoans known in the Adriatic Sea, and for about 45% of anthozoans known in the Mediterranean Sea. Eight of these species were not recorded previously in the Adriatic Sea. Eleven species are considered to be Mediterranean endemics. The heterogeneity of substrates and benthic communities is considerable in the Mljet National Park, with anthozoans present on most different kinds of substrates and in a wide range of benthic communities. Remarkably, the colonial coral Cladocora caespitosa builds a large »reef-like« structure in the Veliko Jezero, in the area characterized by strong bottom hydro- dynamism.

ABSTRACT Atlantia is described as a new genus pertaining to the family Dendrophylliidae (Anthozoa, Scleractinia) based on specimens from Cape Verde, eastern Atlantic. This taxon was first recognized as Enallopsammia micranthus and later described as a new species, Tubastraea caboverdiana, which then changed the status of the genus Tubastraea as native to the Atlantic Ocean. -
Inferred Calcification Rate of a Mediterranean Azooxanthellate
Caroselli et al. Frontiers in Zoology 2012, 9:32 http://www.frontiersinzoology.com/content/9/1/32 RESEARCH Open Access Inferred calcification rate of a Mediterranean azooxanthellate coral is uncoupled with sea surface temperature along an 8° latitudinal gradient Erik Caroselli1, Guido Mattioli2, Oren Levy3, Giuseppe Falini4, Zvy Dubinsky3 and Stefano Goffredo1* Abstract Introduction: Correlations between sea surface temperature (SST) and growth parameters of the solitary azooxanthellate Dendrophylliid Leptopsammia pruvoti were assessed along an 8° latitudinal gradient on western Italian coasts (Mediterranean Sea), to check for possible negative effects of increasing temperature as the ones reported for a closely related, sympatric but zooxanthellate species. Results: Calcification rate was correlated with skeletal density but not with linear extension rate, indicating that calcium carbonate deposition was preferentially allocated to keep a constant skeletal density. Unlike most studies on both temperate and tropical zooxanthellate corals, where calcification rate is strongly related to environmental parameters such as SST, in the present study calcification rate was not correlated with SST. Conclusions: The lower sensitivity of L. pruvoti to SST with respect to other sympatric zooxanthellate corals, such as Balanophyllia europaea, may rely on the absence of a temperature induced inhibition of photosynthesis, and thus the absence of an inhibition of the calcification process. This study is the first field investigation of the relationship between SST and the three growth parameters of an azooxanthellate coral. Increasing research effort on determining the effects of temperature on biological traits of the poorly studied azooxanthellate scleractinians may help to predict the possible species assemblage shifts that are likely to occur in the immediate future as a consequence of global climatic change. -

THE STATUS of the SUNSET CUP CORAL LEPTOPSAMMIA PRUVOTI at LUNDY by ROBERT A
Journal of the Lundy Field Society, 2, 2010 THE STATUS OF THE SUNSET CUP CORAL LEPTOPSAMMIA PRUVOTI AT LUNDY by ROBERT A. IRVING1 AND KEITH HISCOCK2 1 Sea-Scope Marine Environmental Consultants, Combe Lodge, Bampton, Devon, EX16 9LB 2 Marine Biological Association of the UK, Citadel Hill, Plymouth, Devon, PL1 2PB Corresponding author, e-mail: [email protected] ABSTRACT The findings of a survey of the numbers of the nationally rare sunset cup coral Leptopsammia pruvoti at Lundy in September 2007 are presented together with more recent observations. Counts of individuals were undertaken using divers and in situ photography. An estimate is given of the overall size of the coral’s population at Lundy, its extent and its condition, and the proportion of new recruits within the population. The findings are compared with other studies undertaken at Lundy since the early 1980s. These comparisons show dramatic declines in numbers in some areas but increases in others. Keywords: Lundy, Leptopsammia pruvoti, decline, underwater photography, SAC, MNR INTRODUCTION Within British waters, the small but eye-catching sunset cup coral Leptopsammia pruvoti (Lacaze-Duthiers, 1897) (Plate 1) is a species of particular marine natural heritage importance. It is nationally rare (i.e. it occurs in eight or fewer 10 km by 10 km Ordnance Survey grid squares containing sea within the 3 mile limit of territorial seas around Great Britain), and, since 1999, it has had its own Biodiversity Species Action Plan (UK Biodiversity Action Group, 1999). Lundy is a small island, approximately 5 km long by 1 km wide, which lies at the mouth of the Bristol Channel some 18 km from the nearest point of the north-west Devon mainland.
